Error 1935 : while trying to use Office 2010 on Windows 7 o/s

Some weeks ago I had Win7 and Office working just fine, together with everything else on my PC.
Then I had a power failure, which trashed the Boot Configuration Data so that it would not boot. After several attempts I took it to my local IT shop, where they also saw the BCD problem. The following day they pressed to start button (intending to operate from a Linux disk to squirrel away all the data etc...) - but it booted OK into Windows. Or so it seemed.
There were several problems which appeared later - in particular I couldn't update IE (v8), and a .NET update. Also I couldn't connect to my Scanner, or get my PDA to connect / synch.
At this stage I had a PC which with a few shortcomings was OK - ie all of Office was working OK.
I then reinstalled Win 7, via the upgrade option.
We're back up and running - update / scanner / PDA problems have gone away.
But I can't use my Office programs.
Using Word as an example, when I try to run it, it says "Please wait while Windows configures Microsoft Office Professional Plus 2010." It then fails with Error 1935 - an error occurred during the installation of assembly component {63E949F6-03BC-5C40-A01F-C8B3B9A1E18E} HRESULT: 0x800736FD.
I checked the registry for the assembly component but it's not there. However under Computer/HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Components... there is the same entry except that the string A01F is showing FF1F in the registry.
From the right hand pane: File REG_SZ ul_manifest.63E949F6-03BC-5C40-FF1F-C8B3B9A1E18E
Is this a clue?
There are two users on this machine.
When I tried to use Word in 2nd User, I got the Please wait... and the Error 1935 - but then it opened Word, and Word seems to be OK. However when I try to start Excel (never previously used by 2nd user, I get the same error 1935, and cannot get past that.
Other research on the net makes .NET an issue - I have .NET v4 installed.
My a/v is Kaspersky - suspending it made no difference.
Sorry for such a long essay, but I've run out of ideas?

Using the Cleanup Tool, uninstall .Net Framework 1.0, 1.1, 2.0. 3.0 and 3.5 (The cleanup tool won’t allow you to remove the .NET Framework 2.0 on Vista and higher because it is installed as an OS component.)

Install the downloaded updates in this order (the order is very important):

.Net Framework 3.5 SP1

.Net Framework 1.1

.Net Framework 1.1 SP1

Restart the computer and try installing Office

Hi big one 01,
Thanks for your response.
Tried the above - same failure mode on trying to run Word in user1. However USer2 can still use Word.
I am of course not really wanting to reinstall Office - it's obviously still there after the upgrade. I haven't had to re install any other software.
I now seem to have .NET 1.1 installed.
Windows Update is inviting me to install .NET Framework 4 Client Profile for Windows 7 x86 - what should I do about that?
And I am still no closer to seeing my Outlook Calendar.
Further advice would be welcome?

Veeam is happy to provide a free NFR license (1 year, 2 sockets) to all certified IT Pros. The license allows for the non-production use of Veeam Availability Suite v9.5 in your home lab, without any feature limitations. It works for both VMware and Hyper-V environments

You will see from my previous post that I completely removed .NET.
I then installed as requested by big_one01:

.Net Framework 3.5 SP1

.Net Framework 1.1

.Net Framework 1.1 SP1

These are today's downloads.

It appears (from the program delete display) that I now have .NET 1.1 installed. However .NET v 2 is integral with Windows 7 , so I assume that .NET v2 is still there somewhere.

And I am invited by Windows Update to download & install .NET 4.

So I don't understand your proposed way forward?

Regards,

Vaughan

VaughanMx,

OK, if the .NET fixes did not work, have you tried reinstalling Office? Uninstall, clean files, and registry.
another thing you could try is create a new profile. if you could use Office with the latest profile you created, the prev. profiles might be corrupted.

Hi selintung:

I might be missing something here - but how would I create a new profile if I can't get Outlook started?

The actions relating to .NET were a waste of time.
My Office package was a download - so guess where the Product Key was? - right - in my email (Outlook) - bother!
installing Thunderbird and importing my Outlook email stuff resolved that one.
The installation process did not require a new profile.
